Исследована проблема распознавания лиц в масках. Показано, что разнообразные по форме, текстуре и цвету реальные маски создают проблемы для современных систем распознавания изображений лиц. Одна из таких причин — отсутствие необходимых реальных наборов обучающих данных. Создание новых данных на базе простых методов формирования масок на изображениях лиц может решить эту проблему.</p></sec><sec><title>Метод</title><p>Метод. Предложен оригинальный метод, включающий генерацию различных типов, форм и цветов масок непосредственно на оригинальной текстуре изображений лиц. При этом учитывалось формирование масок на лицах отдельных людей, лицах в групповых фото и в сценах с потоками людей.</p></sec><sec><title>Основные результаты</title><p>Основные результаты. На основе 100 оригинальных изображений лиц из базы «СUHK Face Sketch Database» создана тестовая база, которая включает в себя более 20 000 изображений лиц с масками, доступных для использования. Выполнены эксперименты по распознаванию лиц тестовой базы в рамках реализованных четырех систем: трех современных на базе «глубокого обучения» и одной детерминированной — на базе косинус-преобразования. Оценена результативность этих систем, интерпретированы полученные результаты распознавания лиц в масках и отмечены маски, которые были проблемой для выбранных систем.</p></sec><sec><title>Практическая значимость</title><p>Практическая значимость.

It is shown that real masks of various shapes, textures and colors have become a problem for state-of-the-art face recognition systems. A reason for this is the lack of the necessary real training datasets. Creation of new data based on simple methods of forming masks on face images could solve this problem. An original method is proposed including the generation of various types, shapes, and colors of masks directly on the original texture of face images. The formation of the masks on the faces of individuals, on faces in group photos, and in scenes with streams of people was taken into account. Based on 100 original face images from the CUHK Face Sketch Database, a  test database was created that includes more than 20,000 masked faces images which available for use. Experiments were carried out to recognize faces from the test database within the implemented four systems, among which three are state-of-the-art systems based on “deep learning” and one is deterministic system based on the cosine-transform. The performance of these systems was evaluated, the obtained results of masked face recognition were interpreted, and the masks that were a problem for selected four systems were noted. The proposed mask generation method can be used to create corpora and test databases of images with masks. The obtained results will be useful to researchers and specialists in the field of image processing and analysis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>генерация масок</kwd><kwd>распознавание изображений лиц</kwd><kwd>антропометрия лица</kwd><kwd>нейросети</kwd><kwd>экстрактор признаков</kwd><kwd>метрика косинусного подобия</kwd><kwd>критерий минимального расстояния</kwd></kwd-group><kwd-group xml:lang="en"><kwd>masks generation</kwd><kwd>face images recognition</kwd><kwd>facial anthropometry</kwd><kwd>neural networks</kwd><kwd>feature extractor</kwd><kwd>cosine similarity metric</kwd><kwd>minimum distance criterion</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке проекта фонда РФФИ № 20-04-60529-вирусы, а также частично в рамках бюджетной темы № FFZF-2022-0005.</funding-statement><funding-statement xml:lang="en">The work was supported by the RFBR project No. 20-04-60529-viruses, and also partially under the budget topic No. FFZF-2022-0005.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ge S., Li J., Ye Q., Luo Z.
